It seems that we explicitly disable certain mochitest-chrome tests in dom/plugins/test/mochitest/Makefile.in when there is no crash reporter enabled, but there are also tests in mochitest-plain that require it to be enabled to work properly:
74 ERROR TEST-UNEXPECTED-FAIL | /tests/dom/plugins/test/test_crashing.html | This test did not leave any crash dumps behind, but we were expecting some!
372 ERROR TEST-UNEXPECTED-FAIL | /tests/dom/plugins/test/test_hanging.html | This test did not leave any crash dumps behind, but we were expecting some!
This is turning ASan builds orange on mochitest-3 so I would like to fix this by enabling these tests only when the crash reporter is enabled.
Any test with "crashing" in the name ought to only be enabled when the crashreporter is enabled.

These changes make the tests pass in that sub directory, even with the crash reporter disabled.
